WebEx Audio Overview

You can use your phone or your computer to hear and speak in a WebEx event:

  • Phone: You can use the Call Me service, if your site supports it, to receive a call from the event, or you can call in.



    This option typically provides good voice transmission, but may have a cost attached.

  • Computer: With a headset connected to your computer, you can join the audio portion of the event.



    This option sometimes causes noisy transmission, or an irregular voice stream, but has no cost attached.


Up to 1,000 participants can connect to the audio conference using WebEx Audio—500 using the phone and 500 using the computer to connect over the Internet. All 1,000 participants can speak.

You can switch between audio connection types with little or no listening interruption.
